Model PLZ1002W Electronic Load is rated for loading voltage 3 - 110 volts, loading current 0 - 200 amperes, and wattage 1000 watts. The PLZ1002W can be operated either in a constant current mode or in a constant resistance mode. The PLZ1002W allows dynamic load test by switching between two different levels of load current with its internal oscillator and electronic switching circuit. This function is available when in either the constant current or resistance mode. The PLZ1002W is incorporated with protectors against overvoltage, overcurrent, overpower, and reverse polarity connection. It has a digital voltmeter/ammeter of 3-1/2 digits. It has a fan for forced air cooling. Features (1) The PLZ10Ö2W employs power MOS FET, thereby eliminating secondary breakdown and improving the reliability. (2) A digital voltmeter/ammeter of 3-1/2 digits is provided. (3) Two 10-turn helical potentiometers are provided to set individual levels of loading current. (4) The loading current can be switched between two different levels, thereby allowing dynamic load test. (5) The loading current can be remote-controlled with a voltage signal (when in the constant current mode) or with a resistance signal (when in the constant current or resistance mode). (6) Two or more units or PLZ1002W can be operated in parallel in a master-slave mode. (7) The PLZ1002W is incorporated with protectors against overvoltage, overcurrent, overpower, overheat, and inverted connections of input. These protectors reset automatically, (8) The PLZI002W is incorporated with a rapid-response rush current suppression circuit. (9) Optional frames and brackets are available to install the PLZ1002W on a rack of the EIA Standard or the JIS Standard.
